The North Slope of Alaska has concentrations of air pollutants comparable to the air pollutant concentration of some major cities on the east coast of the United States because А .the snowmobiles used by the people of the region pollute significantly more than cars and trucks
B .the region is currently undergoing an industrial boom
C .pollutants are transported by air from Eurasia
D .volcanoes in the region naturally release large amounts of particulates
E .the cold weather prevents the dissipation of pollutants

The answer is    (d) 7/2======we have    we also  have an integral      notice how function f splits up at x = 0. there's a left piece and a right pieceso we'll need to do the same thing with our integral: split it at x = 0we use a property of integrals that allows us to split up and sum:     notice that for the piecewise function f, the function has the equationf(x) = x when x  ≤ 0. so for the integral  , f(x) = x so it changes into      for the piecewise function f, the function has the equationf(x) = x+1  when x  > 0. for the integral  , we have    therefore, back to our splitted integral:    

Ais correct according to edgenuity

You this is right
